I read a lot of PDF files in preview. Whenever I open a file, switch to fullscreen to have a view in which I can focus on reading the PDF without being distracted, after 5 seconds, preview.app goes to the second page. I understand that this is great for photos. At the same time, it's really stupid for PDF files with lots of text. So this function should either be file format sensitive or if that is too much to ask for apple to implement, there should be an option to disable auto-play for fullscreen view.
I was unable to find such an option in the preferences for preview.app. Am I the only one reading PDFs in fullscreen and annoyed by this behavior? Or did I miss a setting?
